AC Infinity CLOUDLAB 743D Review: 2-in-1 Grow Tent

Short answer: the AC Infinity CLOUDLAB 743D solved a real space problem for me. Its main 3×3 chamber handled larger plants while the stacked side chamber kept smaller plants moving behind them. The tested tent felt sturdier than cheaper tents I had used, but the removable divider was fussy, could leak light and interfered with the spill trays.

Who this tent layout is for

A divided tent makes sense when floor space—not equipment—is the limiting factor. I used the main chamber for larger plants and the stacked side for smaller stages, allowing one cycle to start before the previous cycle finished.

Assembly and material notes

The heavy poles were the first quality difference I noticed. Pair the frame pieces until their spring buttons click, lay the shell flat if the room allows it, then work the assembled frame into the canvas without forcing a sharp corner. I found it easier to add the shelves after the main shell was positioned.

The reflective lining and exterior fabric felt heavier than several tents I had owned, but “thicker” does not mean puncture-proof. A dropped 35-pound light punctured my removable spill tray. Keep sharp hardware away from the shell and use a second person when hanging heavy equipment.

The divider is the main compromise

The optional divider uses hook-and-loop material, so the alignment must be patient and exact. A small gap can pass light between chambers. The divider also covers frame sections used to secure the spill trays, leaving their inner edges looser than I wanted.

Before trusting different photoperiods, close the room, run the brighter chamber and inspect the darker side from every angle. Also confirm that each chamber can exchange or exhaust enough air; three physical sections do not automatically create three controlled environments.

AC Infinity’s current CLOUDLAB 743D page lists today’s model as 48×36×72 inches with a removable wall and tray. The current CLOUDLAB manual should be the final authority for assembly and load instructions.

Frequently asked questions

What size is the CLOUDLAB 743D?

The current manufacturer listing identifies it as a 4×3-foot overall tent measuring 48×36×72 inches. Verify the exact current listing before ordering.

Can the side chamber run a different light schedule?

That is the intended use, but inspect the removable divider for light leaks and plan separate lights, airflow and environmental sensors.

What was the biggest problem in the test?

The divider required careful alignment, could pass light and blocked one secured edge of the spill trays.

Is a divided tent better than two tents?

It saves floor space, but it also concentrates equipment and reduces flexibility. The better choice depends on your room, plant height and cycle plan.
